Abstract (en)

[origin: US4283320A] An opacified latex paint comprising small particle film-forming latex binders in combination with minor amounts of opacifying pigment, and substantial amounts of non-film-forming polymeric particles (plastic pigment) provides a semi-gloss latex paint composition having excellent hard enamel surfaces along with desirable film integrity properties. The plastic pigment particles are between about 0.1 and 0.5 microns and contain 0.2 to 2% copolymerized monomers containing carboxylic acid groups. The semi-gloss plastic pigment latex paint is compounded at pigment-volume-content (PVC) between about 30% and 45% and considerably higher than conventional high quality enamel latex paints. The opacified semi-gloss paint films exhibit excellent physical properties such as hard enamel surfaces, scrub resistance, burnish resistance, mar resistance, stain resistance, and other desirable paint film integrity properties.
